Hello My videopad has started to export wmv videos with a black screen all the way through but sound is ok. Bit of background, I am using win7, plus I'm using an earlier version of videopad because when I got may latest computer, I downloaded the latest version of videopad and I noticed the crop feature was no longer available. So I searched out an earlier version that had the crop feature. Don't know if this relevant at all. Will updating the software sort out the problem, but I don't want to loose the crop tool as it is something I use most in my editing? Please help, thank you Steve
